JOHN F. MILLIGAN, OF ST LOUIS, MISSOURI.

ream Patent No. 83,079, dated October 13, 1868.

mrnovsn BALING-PRESB.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

- Be it known that I, J OHN F. MILLIGAN, of St. Louis, in the county ofSt. Louis, and State of Missouri, have made certain new and usefulImprovements in Baling- Presses; and I do hereby declare that thefollowing is a full and clear description thereof, reference being hadto the accompanying diawings, and to the letters of reference markedthereon.

- This invention relates to a new combination of the toggle-joint andprogressive lever, for the purpose of operating the movable platen of abaling-press.

To enable those skilled in the art to make and use my improved press, Iwill proceed to describe its construction and operation.

The accompanying drawings represent a sectional elevation of theimproved press. The frame A may be of any desired form of constructionthat may be found adapted to the style of press herein represented. Thestationary platen B, and the movable platenG, may also be of any desiredform of construction. The driving-shaft D will have its bearingsprovided in the hangers a, attached to the frame A, and each end of thesaid shaft will be provided with endless screwthreads (1, which willgear into and actuate the cogged sectors D. The links or connecting-rods'E will be attached to the sectors by means of the wrist-pins e, andalso to the joint-pin g, of the toggle-joint rods G. This arrangement ofthe sectors and connecting-rods gives all the benefits derived from theuse of the progressive lever of the Tyler and other presses. The fixedends of the rods G are provided with hearings in the joint-blocks g,which are attached tothe frame A, and form the fulcrum against which thepressure is exerted to compress the bale. A joint-block, g, similar tothe blocks is fixed to the platen C, for each of the movable ends of therods G.

In the operation of a press constructed as above described, the sectorsand rods E, act with a progressive leverage, and the toggle-jointrods G,act in concert with the greatest force at the moment of ultimate strainor pressure upon the bale.

The press herein described may be considered as a double-acting ordouble-geared press. A single-geared press of equivalent constructionmight be produced .by the use of only one sector, D, and rod E, byturning both of the toggle-joints'inthe same direction, and-- using aconnecting-rod between the two knuckles of the toggle-joint rods.

If used as a single-geared press, it would become necessary to place,fiiction-sheaves, c, at the ends of the platen O, for the purpose ofreducingthe excessive lateral pressure that would, by such construction,be produced, It would, however, be beneficial to use the said sheaves cat all times, and in all forms of con- -struction.

I am were that all the several devices herein described, consideredseparately, are old and well known; and, further, that the combinationof a screwshaft, worm-wheel or sectors, connecting-rods, and the platensof a press, is not new, but has been described in patents alreadyissued; hence I do in nowise claim said individual devices, nor the.combination before mentioned; but

What I do claim as my invention is- Gombining the screw-threaded shaftD, sectors D, and platen C, the toggle-levers G, and rods E, in themanner herein shown and described.

JOHN E MILLIGAN.
